If an excess of sulfric acid reacts with 23.0 grams of sodium chloride how many grams of hydrochloric acid are produced? 2H2SO4 + 4NaCI -> 2H2SO4 + 4HCI
Answers
H₂SO₄ = 98.0 g/mol
H₂SO₄ + 2 NaCl = 2 HCl + Na₂SO₄
98.0 g H₂SO₄ -----------> 2 x 58.44 g NaCl
? g H₂SO₄ ------------> 23.0 g NaCl
Mass of H₂SO₄ = 23.0 x 98.0 / 2 x 58.44
Mass of H₂SO₄ = 2254 / 116.88
=> 19.284 g of H₂SO₄
hope this helps!

Nuclear fusion in the sun involves hydrogen (H) atoms combining to form helium (He). A student claims that since the atmosphere contains hydrogen, any fusion reaction on Earth would result in an uncontrolled chain reaction. What is wrong with the student's reasoning?The hydrogen in air is not densely packed enough for an uncontrolled chain reaction. Uncontrolled chain reactions can only happen during nuclear fission. It is impossible to cause a fusion reaction to happen anywhere outside of the sun. We are safe because there is no radioactive hydrogen in the air.

Final answer:
The Lewis structure for the molecule CH3CH2NH3+ (ethylammonium) showcases hydrogen atoms bonded to carbon and nitrogen atoms. The positive charge resides on the nitrogen atom.
Explanation:
The molecule CH3CH2NH3+ is also known as ethylammonium, a form of a substituted ammonium ion. The Lewis structure of this molecule can be drawn based on the concept that hydrogen has one bond, carbon has four bonds, and nitrogen has three bonds and one lone pair of electrons. The positive charge in CH3CH2NH3+ is located on the nitrogen atom.
Here’s a simple way to draw it:
1. Draw a C atom connected to three H atoms, signifying the CH3 group.
2. Draw another C atom bonded to the first C and two H atoms, signifying the CH2 group.
3. Draw the N atom connected to the second C and three H atoms, signifying the NH3 group.
4. Mark a + sign near the N atom to indicate the positive charge.

When something is oxidized, it loses electrons.
When something is reduced, it gains electrons.
So the correct statements would be the second to last and third to last statements
The correct statements are -
- An element has been oxidized when it has reacted with oxygen gas to produce a compound with the oxygen atom included in its formula,
- A compound has been reduced when it originally had an oxygen atom in its formula and lost it as a consequence of reacting with some other element or compound,
- An element has been oxidized when, as a consequence of a chemical reaction, it has lost electrons to produce the same element as a product with a more positive oxidation state and
- An element has been reduced when, as a consequence of chemical reaction, it has gained electrons to produce the same element as a product with a more negative oxidation state.
Oxidation state, also known as oxidation number, is a measure of the degree of oxidation or reduction of an atom within a compound or ion. It indicates the number of electrons that an atom has gained or lost, or the hypothetical charge that it would have if all the shared electrons in a compound were assigned to the more electronegative atom.
The oxidation state of an atom can be positive, negative, or zero. In a neutral molecule, the sum of the oxidation states of all the atoms must be zero. In ions or compounds, the sum of the oxidation states of all the atoms must be equal to the overall charge of the species.
Oxidation states are assigned based on a set of rules that consider the electronegativity of atoms, the number of valence electrons, and the distribution of electrons in a molecule or ion. The oxidation state provides information about the reactivity, bonding, and redox reactions of substances. It is often represented by Roman numerals or as a signed integer.

Answers
The percussion instruments are a drum, which makes sound when a mallet hits its surface and a cymbal, which makes sound when it is crashed against another cymbal.
What are percussion instruments?
Percussion instruments generate sound when struck by an object. Among the options provided, the drum and the cymbal are indeed percussion instruments. A drum produces sound when a mallet or stick hits its surface, causing vibrations that create the characteristic drumming sound. Similarly, a cymbal produces sound when it is crashed against another cymbal or struck with a mallet.
So, the percussion instruments that fit the description of making sound when struck are the drum and the cymbal. These instruments belong to the percussion family, which is characterized by its reliance on impact to produce musical tones.
